PXE Boot HP X2 210 (Hybrid tablet Windows 10 Pro)

[Matthieu Jacquart]

Hi,

We’ve just bought 32 HP tablet X2 210 (not really a tablet because it runs under Win 10 Pro…), which has USB 3.0 but no network port.
Like other people, I tried to boot on PXE with USB to RJ45 adapter I found on a store near my office (ASIX AX88772C)
It’s an UEFI bios so I had first to disable secure boot and it didn’t work with undionly.kpxe.
If I specified an efi boot file (ipxe.efi or snp.efi), I’m able to boot on network, retrieve IP address and display Fog menu.
BUT… That’s all…Any option I choose, screen stay black after loading file bzimage and initzx (for quick image I can enter credentials and choose image, but same problem after that)

What can I change to complete task as quick registration or else ?

Thanks for help, and my apologize because there are several topics on that subject, but each computer/adapter seems specific…

Matthieu

You are right, it seems to be a common thread with the tablets this week. There is something in the linux boot kernels that does not like these tablets. I think we really need to find out the geometry/layout of these devices.

If you can, please try to usb boot a linux live image on these tablets. Pick the latest release of ubuntu desktop. If you can get that running then we can run a few commands like lsblk and lspci to find out the exact structure of the storage and devices installed in the tablet.

@george1421 As it’s not getting that far in, I think it’s driver related on the iPXE side.

Maybe, try the intel/realtek.efi files?

[Sebastian Roth]

@Tom-Elliott Maybe I am wrong but I think George is right about Matthieu’s request. Sounds like iPXE is working fine (using ipxe.efi/snp.efi) as it comes up with the menu.

Any option I choose, screen stay black after loading file bzimage and initzx …

Black screen after loading the kernel. It could still be related on how iPXE is loading the kernel on those devices but we don’t know yet I reckon.

[Tom Elliott]

@Sebastian-Roth The only other time I have seen the black, is the files are html files, not actually downloaded files (bzImage/inits).

[Matthieu Jacquart]

@Tom-Elliott I’ve just tried intel and realtek.efi,

DHCP failed...

First time (in my original post) I tried ipxe, snp and snponly.efi, and always black screen after bzimage and init.xz…

[Sebastian Roth]

@Tom-Elliott Hmm, but I guess Matthieu’s setup is working for other devices, right?

@Matthieu-Jacquart As you are using FOG trunk (signature), can you please try to increase kernel loglevel and enable debug. You can find those settings in FOG configuration in the web GUI. Maybe we see some more info then.
As well I really like George’s idea to boot any kind of live Linux from an USB thumb drive to see if you can get Linux up at all.

[Tom Elliott]

@Sebastian-Roth I’m still under the impression it’s related to the files not having the right content, but I could be wrong. It happens a TON!

[Matthieu Jacquart]

@george1421
@Sebastian-Roth
I increase FOG_KERNEL_LOGLEVEL to 7 and activate FOG_KERNEL_DEBUG, which log can I look at after ?

I can boot on ubuntu live USB, it works perfectly

[george1421]

@Matthieu-Jacquart My intent was to not send you in 20 directions all at once. But since a live boot works, once you get the debugging information for the devs, it would be interesting to know what the output of lsblk and lspci -m are.

[Tom Elliott]

How about we get:

ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz}

First.

I’m still guessing these files didn’t download properly last time.

[Sebastian Roth]

@Matthieu-Jacquart There is no log file. You will see more output on the screen when your tablet boots up - if so. But maybe you won’t see any more information. Can you boot other clients properly? Just asking to make sure your kernel/inits are fine.

[Matthieu Jacquart]

@Tom Elliott
ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz} on fog server give me

root@FOG:~$ ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz}
-rw-r--r-- 1 fog www-data 16476332 janv. 21 08:22 /var/www/fog/service/ipxe/init.xz
-rw-r--r-- 1 fog www-data 15448272 janv. 21 08:23 /var/www/fog/service/ipxe/init_32.xz
-rw-r--r-- 1 fog www-data  6847456 janv. 21 08:23 /var/www/fog/service/ipxe/bzImage
-rw-r--r-- 1 fog www-data  6759504 janv. 21 08:23 /var/www/fog/service/ipxe/bzImage32

@Sebastian-Roth Yes other client works perfectly, I deploy image yesterday and no problem. I didn’t see more output when I tried to boot on tablet

@george1421 Ok I’ll give you the result of command on Monday, for now I’m at home

[Tom Elliott]

At least now I know it’s not bad downloaded files and what not.

I’ll reiterate this. This is easy to get and important to know.

[Sebastian Roth]

@Matthieu-Jacquart Hope we’re not asking too many things here from you. But would it be possible to take a short video of the whole bootup process. Sometimes there are small hints that we only see if we have it right in front of our eyes…

[george1421]

Thinking about this a bit more, it would also be interesting to know what modules are loaded by what kernel modules were loaded by the live boot OS. You would use lsmod and probably direct the output into a file.

[Matthieu Jacquart]

Ok guys, I’ll give you this on monday
I hop to find a solution, It seems so close to boot properly on fog server !

OK, let’s go : Video link (really sorry for quality !!!) : https://youtu.be/ob_5qC7KRqs

For test with (Ubuntu 14.04 LTS Live) : something strange, in file explorer ubuntu just see it’s own file system and USB key, but not internal HDD (windows 10 partitions). If I use live USB key on another computer with SSD, Ubuntu displays Windows partitions (Windows 7)

While I’m not sure what this means at this moment, this disk structure does look interesting. Unless I’m reading this wrong (likely) it appears you have 2 or 3 hard drives in this device.
